I have some numeric codes stored in a DataTable. When I try to sort it using DataView it sorts the column by string. What is the easiest way to sort the data as integer/number?
DataView view = dt.DefaultView();
view.Sort = "Code asc";
dt = view.ToTable();
Data in datatable: 128, 123, 112, 12, 126
after sort it shows: 112, 12, 123, 126, 128
expected result: 12, 112, 123, 126, 128
Here is working example. You can create another DataTable via Clone, and change the data type of the column to Int and copy the data.
DataTable dt = GetTable(); // Assume this method returns the datatable from service
DataTable dt2 = dt.Clone();
dt2.Columns["Code"].DataType = Type.GetType("System.Int32");
foreach (DataRow dr in dt.Rows)
{
dt2.ImportRow(dr);
}
dt2.AcceptChanges();
DataView dv = dt2.DefaultView;
dv.Sort = "Code ASC";
